I will guess that this is your answer to "Are you familiar with the Quadratic Formula?", and that you actually mean "(-b ± sqrt[b^2 - 4ac]) / (2a)". But you have left the other questions unanswered, so we still do not know what you are needing to do.Tascja said:yes... x = -b +/_ SqRt b^2 -4ac all over 2a...
